I actually find that handy for use with my laptop--unplug the HD, import my "core library" (about 30GB), then plug it in and import the rest (over 200GB at this point.) Thus, when I'm out and want to listen to something, I still have all my favorite songs; just not everything (which wouldn't fit on my laptop's HD, anyway.) Basically, it turns the internal HD into a not-too-smart cache of the external one. (On that note, if there's a program that provides this internal/external storage caching mechanism more intelligently and on a larger scale, I'dclove to hear about it.)
